Nested families flexing is not consistent.

So here's a door family that has a nested Panick bar(generic family). The length of the Bar is controlled with the formula (Width -300mm). It all works, flexes perfectly until I load the door in a project.

For some reason, the flexing is not consistent. Can someone point where I am going wrong?

 You are currently locking the PB geometry to the side using a dimension...You need to lock it to ref. plane of the door. ie:

  1. edit the Panic bar family
    • add the necessary ref planes which will be used to lock in Host family
    • add Left right flip control (rotating the bar when in the host will reverse the orientation of the alignment plane - you need to use flip controls or mirror it) 
  2. In the Host family you need to
    • add a ref. plane @200mm where the Knob/Handle/Panic will be locked 
    • You need to add a ref plane at the gegenbandseite of the leaf and associate that with the Thickness parameter

Wow. That worked like a charm. I have been trying to get my head around all the things you changed. And I managed to get it to Flex properly!

 

 

Is there a reason you made the PB length as a type parameter? (It was Instance before so I could snap the lengths in host family)

 

Is it really crucial to set the type of a reference plane? (like right, left, etc?)

 

thanks again! :leicht_lächelndes_Gesicht:

No it is not, but you need to be consistent with the way you constrain nested elements

  1. When locking nested components, you should lock them to reference planes and control those reference planes using dimensions strings/parameters. 
  2. Working with both locked references and snap locked shape handles at the same time is not really recommended and rarely work as expected 
    • Either lock references and associate parameters
    • Or Snap lock shape handles to control the length and width
  3. You can use both type or instance...if it is shared nested components you would definitely need to work with instance parameters otherwise you wont be able to associate them to parameters in the host. I used Type considering that the nested components were not shared

Ok, So it worked perfectly with flexing until I tried to give the combine the handle bar options.

here's the updated family. I added the ref planes as you suggested. no Snap-locking for length.

 

Do you where I am going wrong?

 

 

Funny enough for me it happens only on the "Bandseite" where I placed the family with a flip.
